Can I replace just one ignition coil?
You can replace one coil at a time or all at the same time.
I would however recommend having all spark plugs replaced with the coils so you do not have to remove coils twice..
How long do coil packs usually last?

No, it must be grounded to the cylinder head that the coils are discharging to. Grounding to the frame is a bad idea.
What happens if you don’t change your ignition coil?
What if I don’t replace it? A vehicle with one or more faulty ignition coils will lack power and run poorly, or sometimes not run at all. Additionally, running a misfiring engine for extended periods can damage the catalytic converters and oxygen sensors due to unspent fuel making its way into the exhaust system.
How can you tell if an ignition coil is bad?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected, measure the coil’s primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter.
Should you replace ignition coils with spark plugs?
Time and mileage are enemies to your vehicle’s ignition wires and coils. Whenever you change spark plugs, it is a good idea to replace the ignition wires and vice versa. This will keep your vehicle running at peak performance and prevent you wasting money on unburned gasoline.

Do coil packs increase horsepower?
Many years ago, on even a slightly warmed up car, there was often some power in a slightly larger gap and a higher output coil. Anything modern enough to have individual coil packs, any gain is probable to be more from replacing units with 100k miles on them than any actual power increase.
Should you replace all coil packs at the same time?
Coil packs are reliable and likely to last the lifetime of a vehicle. If anyone goes bad, there is no need to change all of them. However, if one pack starts malfunctioning after the odometer has around 75,000 miles, you should replace them all.
Are coil packs interchangeable?
Yes, they do interchange with each other. been designed with both durability and performance in mind.
Are all LS coil packs the same?
The big connector by fuel rail is the same on all LS stuff? As far as connectors are concerned, yes, the engine harness to coil harness connector is the same regardless of which coil harness you choose. The coil end plug is different. There’s LS1/6 style and then there’s LS2/3/5/7 and all the truck motors.
How often should ignition coils be replaced?
around 100,000 milesThe ignition coil on car is supposed to last around 100,000 miles or more. You will have reduced gas mileage when coil begins to go bad and becomes less able to transfer power. Your car requires more fuel to run, this means you will spend more money on gas than normal.
Will ls3 coils work on ls1?
Was told by MSD that LS3 coils will NOT work on a LS1 engine, even if you figure out how to connect them. Something about coil “frequency” or such. You need LS1 coils, although I’ve read of some using “truck” coils, but I suspect they are LS1 design with different output.
